When she was ten years old, by chance, Mu Qing entered the palace and became a little guard beside the princess.
Brother Guard, you are so handsome. How about playing with Xiaojin?
When he was thirteen years old, Mu Qing made the princess sad due to his negligence. The palace servants bullied him and punished him heavily. However, the princess hugged him and said, "It's all Xiao Jin's fault. If Xiao Jin hadn't cried, you wouldn't have been beaten. From now on, Xiao Jin will never cry again, okay."
That year, he made a promise in his heart to protect her forever.
The introduction is useless, the name is useless, in short, this is a story of mutual protection.
